Format of /proc/bus/pci/devices file.

Hello,
Can anyone tell me what excactly the fields are in the /proc/bus/pci/devices file, I'm using 2.6.12 and have /sys mounted as well but I'm interested in /proc/bus/pci/devices for the time being.
The following entry is describing my pci sound card from ensoniq:

0060 12741371 5 0000ef01 00000000 00000000 00000000
00000000 00000000 00000000 00000040 00000000 00000000
00000000 00000000 00000000 00000000 ENS1371

The forth entry, 0000ef01, is the base ioport for the card?
The second entry seems to be the vendor id 0x1274 and the product id 0x1371 slapped together. Where can I get more info about this file? I'm really interested in what the vendor id is describing, where it comes from, if it has a representation under windows etc.

Any help you could give me on this would be kewl.

You might want to try the lspci command instead of trying to decipher this file on your own.

Code:

# lspci -vv

would be a good place to start!

Hey thanks.

I've been looking at lspci, and the man page for it. Its the pci ids (lspci -vvnb) I'm really interested in /usr/share/hwdata/pci.ids has a list of them, but where do they come from are? they encoded on the card, specific to linux etc? Thought my query was more software then pci based, Sorry.
